Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
*=multiplication symbol /=division symbol r*(r*ㅠ)=r2 ......... radius*(radius*pi)=radius2 ........... radius times the radius times pi equals radius squared HINT HINT HINT an easier way to put this is .......... d*ㅠ/2=n ............. diameter*ㅠ/2=answer .......... diameter times pi divided by two equals the answer
Not necessarily. If it is a semicircle - a circle bounded by an arc and the diameter of the original circle, it has two vertices - at the end of the diameter. However, a half circle need not have a side that is a straight line. It can be like the yin-yang symbol (see link). The half circle here has no vertex.
It was popularized by Leonhard Euler, when he adopted the symbol in 1737. By this time, Euler was already a fairly prominent mathematician, serving as head of the mathematics department at the Academy at St. Petersburg. As far as modern historians know, the symbol was first used for that purpose in print in 1706, by Welsh mathematician called William Jones. Prior to that, the symbol for pi was used for the circumference of a circle, not for the (constant) ratio of that circumference to the circle's diameter.
If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
d or ø
The diameter.
In architectural or engineering drawings, it is the symbol for diameter
The symbol you are referring to is likely the "caret" symbol, which is commonly used to indicate exponentiation in mathematical expressions. It is not a standard mathematical notation for representing the number Pi.
Archimedes
It is defined as the ratio of the circumference of a circle to its diameter
What exactly do you mean by "outside" diameter? C=d(3.14) This is supposed to be the symbol pi but I didn't know how to do it on my computer.

Measure the diameter. Multiply the diameter by Pi, this will give the circumference. Pi is approximately 3.1415927 You can use the Pi symbol on a scientific calculator or use 22/7.
π - the ratio of a circle's circumference to its diameter.
pi is represented by the Greek letter (of the same name) π and is the ratio of the circumference of a circle to its diameter.
"Pi" is the symbol almost always used to represent the ratioof the circumference of any circle to its diameter.
